Be it known that I, FEEDEnI/CKW. Liaison; a citizen of the United States, andl vresiding at Baltimore city, State of Maryland,*h`ave invented certain new and 'useful Improve#` cation.

kThis invention relatesto assembling and transfer `mechanism for typographie ma-.

, .chines and particularlyV machines of the cation, Serial character disclosed in my copending applito the casting mechanism vof the machinek and more particularlya mechanism of the,`

v kind mentioned in which manual operations other than the mere depressionof keys are obviated. Other objects are to provideimprovements in various `details of construc-` tion by which mechanism of thisv kind is simpliedn and rendered more vefficient and quiet in operation.

ylfn order to support the.. rear endl offan assembled., line of.l matrices While thev same is being transported tothe casting mechanism ofy thea-.machine the following `rut-lelie.;` nism is provided A vertically slid'able lll) finger 40 is mounted on the front end ofl assembler slide is provided with anv up-y wardlyprojecting lug 42 which is adapted to engage a stop orv abutment 43:L formed on the fixed plate 43 which'limits the movement of the transfer slide to the right. A latch 44 pivoted at 45 is positioned to engage the front face of the lug 42 when the saine contacts with thc stop 43a. The latch 44 serves to hold the transfer slide at thel eX- treme limit of its movement toward the right, as shown in Figure 1 of the drawing. In orderto permit movement of the transfer slide toward the left the latch 44 must be disengaged from the lug 42 and mechanism isY provided to effect such disengagement and to simultaneously raise the finger 40 so that the same willbe positioned to support the rear of the assembled line as the slide is moved. Such mechanism will now be described. f f

The transfer slide as a whole `is moved back and forth through the medium of a connectingrod or spring link. which is given a reciprocating motion from a slotted lever 5l pivoted at 52 to the frame of the machine and operated by a bell crank lever 53wl1ich is alsopivoted to a fixed point on the machine frame and provided with a part which projects into the slot of the lever 51. The bell crank lever 53 is operated by a ,con-

necting rod 54 to which motion is imparted in a manner hereinafter described.

The rod 50 vis connected to thefmember 15 n of the transfer slide by a lost motion connection which comprises a swinging link 55 pivoted at` 56 to said member 15, ythis member vbeing provided with a yfront abut- 'ment 57 and a rear abutment :.58 against which said link 55 contacts alternately as the slide is moved forward and backward.

The link 55 carries aforwardly projectine portion 59 which is adaptedto` contact with the latch 44 and lift the sanieabove the lug 42. This will koccur when the link is swung forward against the abutment '57. luring this motion of thelink 55 the lower end thereof or any part suitably connected therewith will contact with the rear end41b of the lever 41 and move the same about its pivot to elevate the frontend thereof and vthe finger 40.

t will thus be understood that thel The rear end 41by of the lever` slide Operating link moves toward the leftv the latch 44 will be released from the lug 42 andthe finger 40 positioned to Contact with the rear end ofthe assembled line and support the same as the transfer slide continues to move in the'direction stated. The assembled linefis thus transported to the casting mechanism.

moved towardv the right to ,return ther slide positioned against the abutment 58 thus permitting the lever 41 and vfinger 40to drop by gravity totheirnormal position.` AS the transfer slide reaches its original position at the right the latch 44 will again engage the lug42 and hold the` slide in that position.`

The mechanism for operating the transfer slide'-` of the present invention and for controlling the same is substantially like that in my prior application heretofore ymentioned. This mechanism comprises a pulley 60 loosely mounted on a stub-shaft 61 rigidly secured to the frame ofthe machine,

the pulley 60 lbeing constantlyfrotated by a 1t will also be understood that whenvthe slide operating link is original position7 the link 55 will bey beltl62driven from any suitable source (not shown) connected with the machine. On the shaft 61 at one side of the pulley 60 there detachably mounted acam cylinder 63 and on the other side a clutch sleeve 64 carrying a ,clutch disk 65 which is constantly urged toward the pulley 60 by a spring 66. When thespring 66 is vfree to press the clutch disk 65 against the pulley the pulley is pressed against the cam cylindeil 63 and the clutchv disk and cam cylinder rotate with the pulley.. The cam rylinder 63 is projvided with acam groove 63a in which there engages a roller secured to one end ofy a bell crank lever 63?) pivoted at 63 to a Xed part of the` machine, the other end of said lbell crank lever being. securedk to the connected by a link 70 with a starting lever or key 71 on the keyboard of the machine. It will be noted thatlwhen the upper end of the startinglever is pressed down the pin 67 will be withdrawn from the high point f 68 `of the cam ring 68. lf theclutclf disk 65 is not otherwise restrained it will then spring into engagement with the pulley 60 and 'the cam ring' 66 will vmake a complete revolution, causing movement of the bell crank lever 63b and the connecting ,rod 54 which movement will result in advancing the transfer slide towardthe casting mechanisn'i of the machine and returning the same to its original position. One member of the transfer slidejis provided with a yprojection este ` shown) causes the main cam shaft of the machine to maire a single rotation as fully described in my said prior application. The upper end of the lever L has a jointed portion L which is normally maintained in line with the lever by a spring L buty which ivill yield and permit the projection l) of the transfer slide to move toivard the left without moving the lever. In the proper operation of the device the starting hey 7l should be instantly released after being; depressed and the pin 67 then resumes position to engage'the high portion 68 of the cam, ringY 68 and disengage the clutch 'from the pulley after the completion of a single rotation of the cam cylinder. On the end of the clutch sleeve 64; there is secured a second cam ring 7 2 which cooperates with appin 73 on a lever 74- to control the clutch disk G5 in the manner to be hereinafter explained, the cani disk 72 having' a single high portion 72a as shown in Figure ll. The opposite end of the lever 75L carries a roller 7 5 which runs on cam 7 6 on the main cam shaft 77 of the machine, the cani 76 being circular with the exception of a high point 7 6a.

The control of the'clutch disk G5 and the parts operated there jv is effected in the following` manner, Should the starting,` lever 7l be pressed before the main cam shaft 77 of the machine has completed its cycle or before the casting;` mechanism of the machine is in a position to receive an assembled line of matrices, the high point 76 on the cam "7G which is fastened on the cam shaft 77 will not have reached a position to release the bin 73 `from the cam ring 72, it being understood. that the highA point 72a of this cam ringv 72 is timed to be a trifle later in action than that of cam ring` 68. Thus it will be seen that if the lever 7l. is pressed -pieinaturel.f, that is, before the main cani shaft 77 has come to a normal stop the clutch disk G5 vvill be restrained by the action of the pin 73 which will alloiv the transfer slide to move but a` short distance at which point it will be held until the high point 76 on cam 7G disengages the pin 7 3 from the high portion 72 of the cam ring- 72. lV hen this point has been reached the slide Will automatically move forward toward the mold position and complete its'moveinent.

The function and mode of operation of the various parts of the mechanism have been set forth in describing` the same and further description of the operation of the machine as a Whole is thought unnecessary.
